Screening China A-Shares by Turnover While Excluding Beijing and STAR Stocks

Summary

This article presents a China A-share stock screen that selects securities with turnover rates from 3% to 12%, excludes Beijing-listed shares, and omits the STAR Market. It frames the turnover band as a way to focus on stocks with moderate trading activity, then suggests combining the screen with market-trend and fundamental analysis. The article also provides example formula and Python-style implementation ideas for retrieving listed stocks and checking recent turnover.

The screen is a selection rule, not a complete trading strategy: it gives no entry, exit, holding-period, position-sizing, or portfolio rules. It supplies no backtest or return evidence. Its risk discussion notes that the filter may miss popular sectors, that included stocks can still be risky, and that sector exposure may become skewed. The example code also appears inconsistent: it refers to an area field that is not included among the requested stock fields, and the prose’s stated exclusions should be checked against the actual market classifications and data conventions before implementation.

Key ideas

• The screen keeps A-shares with turnover rates between 3% and 12%.
• It excludes Beijing-listed stocks and STAR Market stocks.
• The article recommends supplementing the screen with market and fundamental analysis.
• It warns that the filter can miss hot sectors and produce uneven industry exposure.
• No backtest or evidence of investment performance is presented.
